Bad customer service

On the 28 May 2022 on a Sunday I went to Mr Price Jubilee Mall to buy a jersey I experience a bad customer service from the pregnant woman Mr price stuff member. After I paid I went to fitting room to wear it. When I come back the pregnant lady shouted me and makes funny of me other stuff member where laughing even the customers where laughing I became a joke of the day. I ask her is it how you treat you customers she says yes. I keep quiet because I respected his condition. I was so shock I didn't know what to say. I won't even recommend any person to go to that store they service is very bad. I'm still afraid to go
